Single screw extruder and twin screw extruder have their own characteristics and applications. In some applications, you can choose either single screw or twin screw.

Extruder can be used in plastics industry, food & Pet food industry, chemicals industry, Pharmaceutical, Minerals and Nonwovens industry. This guide mainly introduces the plastic extruder.

Let’s introduce in detail what are the advantages and differences between single-screw and twin-screw extruders.

What's Single Screw Extruder

Single screw extruder means that there is only one screw in the extruder barrel.It is mainly composed of three parts: extrusion system, transmission system and heating and cooling system. Its basic structure is shown in Figure

It can match the meter control system and auto loader and drying system

Extrusion System

The main function of the extrusion system is to melt and plasticize the polymer material to form a uniform melt, and realize the transition from the glass state to the viscous fluid state.The extrusion system mainly includes feeding system, screw and barrel. It is the core part of the extruder, and the screw is the key core component of the extruder.

Application of Single Screw Extruder

Single screw extruder is mainly used in:

Pipe extrusion: suitable for PP PP-R pipes, PE gas pipes, PEX cross-linked pipes, aluminum-plastic composite pipes, ABS pipes, PVC pipes, HDPE silicon core pipes and various co-extruded composite pipes.

• Sheet and sheet extrusion: suitable for the extrusion of PVC, PET, PS, PP, PC and other profiles and sheets.
• Profile extrusion: Adjusting the speed of the extruder and changing the structure of the extruder screw can be used to produce various plastic profiles such as PVC and polyolefins.
